S LIOING MACHINE.

Application filed August 22, 1919. Serial No. 319,059.

To all whom it may concem;

Be it known that I PETER SIvnR'rsnN, a subject of the King of Norway residing in the city of New York, county of Bronx, and

State of New York, have invented certain new and useful Im rovements in Slicing Machines, of which t e following is a specification.

rangement for advancing the object may and preferably does take the form of an inclined reciprocative feedway, as shownin the illustrated embodiment, down which the object slides freely, thereby obviating the necessity for clamping elements and permitting the objects to be more readily changed in the feedway, simplifying the construction and because of the elimination of the clam ing elements permitting the object to be entirely out up.

My invention further provides an arrangement whereby the cutting edge is ef fectually guarded, the central portion of the guarding member being stationary and serving as an aid to present displacement of the object during the cutting operation.

Other objectsand advantages will a pear from the following description an appended claims. V

The drawings accompanying this specification and forming a part thereof illustrate two embodiments of m invention in which:

Figure 1 is aside e evation' of my apparatus. a

Fig. 2 is a fra entary end elevation of the apparatus, s owing a cuttin mechanism and its appurtenances, part y in section.

Fig. 3 is a fragmentary end view of the trafiy regulatin mechanism partly in section. ig. 4 is a agmentary top p an view of the apparatus, on the plane 4-4, of Fig. 2. Fig. 5 is a fragmentar side elevation of a modification of my fee ing mechanism.

Referring to the drawings and particularly to Figs. 1,30 4, a base plate 10, is provided with an upwardly rejecting sleeve 11, preferably integrally ormed with the base plate; and adapted to receive an extension pieceor reduced end 12, at the lower end of a vertical post 13. The upper porto permit tion of this post is inclined to the horizontal, preferably at an angle of 45 degrees. The inclined portion of the post13 is of reduced diameter, forming a stub shaft 13' which carries a rotatable sleeve 14. The lower end of this bearing is su ported by the shouldered portion 15 of t e post 13. A pulley 16 is secured to the sleeve 14, and is held in position by a set screw 17. The pulley is preferably driven by a belt. 18, although obviously it maybe driven b other means. The belt 18 may be actuated by any suitable source of motive power, for instance, b a small electric motor, or if found desirable, it ma be hand driven. The end of the incline lportion of the post 13 has an externaily t readed end 19 of reduced diameter. A circular disc 20 having an internally threaded portion 21 at its center is secured to the threaded portion of the screw 19, thus forming a relatively stationary part to which the appurtenances for guarding the knife edge to be described are secured. This disc preferably ta ers from its center outwardly, so that its t ickest portion is at the center. The center is of such thickness as to correspond to the length of the screwthreaded portion of the end 19.. A rotatable disc 22 is connected to thesleeve 14, in any suitable manner, and'has an annular recess or shouldered portion 23 at its ripheral edge to receive a narrow annu ar knife edge or blade 24. The blade 24 is secured to the disc 22 in any convenient manner, for exam le by screws 25. The disc 22 tapers in are manner describedin connection with the disc 20, sufiicient clearance being provided between the rotatable disc 22 and the stationary disc 20 to avoid contact between the two. A circular uard late 26 is attached to the stationary 18 20 y screws 27. The outer edge of this guard member is turned over so as to provide a de pending annular curtain 28, projecting downwardly a sufiicient distance toadequately rotect the knife edge 24. A portion of t e uard late 26 is cut away at A e kni e to engage the meat in the slicing o ration.

The base p ate 10 is further provided with a plurality of vertical posts 29, 30. 31 and 32 the osts 29 and 30 su porting a horizon-v tal gui e shaft 33, and t e posts 31 and 32, supporting a horizontal guide shaft 34. Shafts 33 and 34 are arranged parallel to each other and receive the slidable bearings and 36. The bearings 35 and 36 carry upwardly projecting brackets 37 and 38, connected by a transverse web 38 having a handle 39'." Each of the brackets 37 and 38 is preferably provided at its upper end with forked member 39 and 40 respectively. The forked members serve to support a feed or guide chute 41 in a osition inclined to the horizontal. Obvious y instead of the pair of shafts and forked brackets, a single shaft, provided with a key-way, so shaped as to prevent rotation of the bearing, might be provided for sup orting the chute 41. The guide chute is 0 any desired shape and is inclined to the base plate as stated, preferably atan angle of degrees, and so arranged that its longitudinal axis is perpendicular to the face of the cutting mechanism and is reciprocable with respect thereto by virtue of the bearings 35 and 36 sliding on the horizontal shafts 33 and 34. The base plate 10 is further provided with a vertical post 42 for carr ing a meat-receiving tray which supports t e end of the meat prior to its contact with the cuttin mechanism, and regulates the thickness of theslices. The lower end of the post 42 is preferably provided with a boss or extension piece 43 of reduced diameter and adapted to rest in a sleeve 44, the latter being preferably integrally formed with the base plate. The upper end of the post 42 has a plurality of radial arms 46, 47, 48 and 49, each of which has a flanged end forming a bearing for shafts to be described. Thebearings of the arms 46 and 47 carry a transverse shaft 49 on which a meat-receiving tray 50 is pivotally mounted by spaced downwardly dependin brackets or bosses 51 and 52. The pair 0 nances, serve to support the portion of the meat-receiving tray adjacent to the cutting mechanism ygwhich is vertically movable,

- whereby thetray may be tilted to any de-' sired inclination, so that its edge adjacent to the cutting mechanism may be raised or lowered 'to any desired extent. The bearings of the arms 48 and 49 en port a transverse rotatable shaft 53 havmg a cam 54 secured thereto in any convenient manner and at any convenient portion thereof, the cam face engaging the lower surface of the meat-receiving tra 50. One end of the shaft 53 is provide with a handle 55, which serves to rotate the shaft 53 and its attached cam 54 to any desired extent. The rotation of the cam causes the variation in the elevation of the tray, as will be readily apparent.

A spring 54' is interposed between the handle 55 and the hearing supporting the shaft 53 to frictionally prevent rotation of the shaft and cam, thus maintainingthe desired elevation of the tray.

In the modification shown in Fig. 5, the

arms 48 and 49 and its appurte-' meat feedin tray. 50, the rotary cutting knife 24 an the guard 26 are similar to those described in connection with the structure shown in Figs. 1 to 4. Instead of the shafts 33 and 34 for reciprocably supporting the feed chute and its appurtenances, a bracket 60 secured to a convenient table, supports the lower end of an upwardly project ing oscillating arm 61, in a bearin 62. The upper end of the arm 61 is rovi ed with a forkedmember or bifurcate end 64 for receiving a feed trough or chute 65, which is inclined to the horizontal in any manner similar to the feed trough 41, described in connection with the structure shown in Figs. 1 to 4. A stop lug 66 is formed with the bracket 60 and limits the movement of the arm 61 and its appurtenances. A recessed boss 67 is preferably integrally formed with the arm 61. and has its major axis projecting substantially at right angles to the longitudinal axis of the arm 61. A rod or bar 68 has one end secured within the boss 67 and extends at right anglesto the longitudinal axis of the arm 61. The bar 68 is screw threaded at 69 and receives a longitudinally slidable counter wei ht 70 which may be shifted to any desire; position on the bar 68 by shifting clamping screws 71, as will be evident from the drawings. The counter weight serves to carry the arm 61 to the position shown in full in the drawings.

In operatingthe'embodiment of my device as shown in i 1 to 4, the meat to be sliced is placed 1n the feed chute 41, which is initially positioned opposite the meat receiving tra 50, as shown in Fig. 1. The meat will s ide down the chute 41 due to its inclination until its end bears on the face of the tray 50. The end of the tray 50 adja- 1 cent to the cutting edge 24 is raised or lowered by means of the handle 55 and its attached cam 54 to a position corresponding to the thickness of the slice desired. The chute 41 is then moved by means of the handle 39 toward the ri ht when viewed as in Fig. 1 until the slice 1s completely severed from the meat. The slice passes under the edge of the knife 24 and drops to a suitable receptacle, which may be laced on base 10. The rotation of the kni e blade 24 is secured as has already been stated b the drive pulley 16, actuated b any suitab e source of motive power. As t e meat is carried across the cutting blade 24, a portion of it rests on the stationary guard member 26 which thus prevents, to a certain extent, the displacement of the meat with respect to the chute 41. The chute 41 is then brought to its initial position, and is ready to sever another slice. It is evident that, with my construction, the chute may be moved to one side, so that access may be readily had to the knife edge. This enables very small pieces to be held in the hand and thus sliced. 13o

In operating the embodiment of my invention illustrated in' Fig. 5, the meat is placed in the chute 65. It slides down the chute in a manner similar to that described in connection with the structure shown in Figs. 1 to 4. The chute 65 is then moved by means of handle 73 in a counter clockwise direction about its bearing 62 until it and the end of the meat which it holds stand opposite to the face of the tray 50. If the handle 73 is now released, the counter weight 70 will move the tray and its arm 61 in a clockwise direction until the meat engages the edge of the rotating cutting knife 24. The weight 70 will continue to force the meat against the cutting knife 24 until the slice is completely severed. The chute 65 may then be again moved to the position for cutting the succeeding slice, indicated by the dotted line in Fi 5. The elevation of the tray 50 is control ed in a manner similar to that described in connection with the structure shown in Fi s. 1 to 4. It is evident that instead of' the counter weight 70, a sprin may be used to perform the same function. Hence, when I speak in my claims of a counter wei ht, I also mean to include a sprin' It is urther evident that oscillation of t e arm 61 and the tray 65 may be secured directly from the source of motive power which drives the rotary cutting mechanism, by the intervention of suitable mechanism.
